OBJECTIVE:To study the effects of indometacin on apootosis and proliferation of cervical cancer Hela cell. METH-ODS:Hela cell was cultured in vitro as study object,and cultured with 0(blank control),200,400,600,800 and 1 000 μmol/L indometacin for 24,48 and 72 h. The inhibitory rate of indometacin to the proliferation of Hela cells was detected by MTT assay. After treated with 0(blank control),400,600 and 800 μmol/L indometacin for 24 h,the change of cellular morphology was ob-served by invert microscope;cell cycle phase and apoptosis were analyzed by flow cytometry. RESUITS:Indometacin of 600, 800,1 000μmol/L could inhibit the proliferation of Hela cell,which was positively correlated to drug concentration and time. Com-pared with blank control,indometacin could induce that Hela cell transformed from polygonous to round in appearance,and result-ed in cell apoptosis and necrosis;the proportion of cells at G0/G1 phase increased,while the proportion of cells at S phase reduced;the apoptotic rate of cells raised. CONCLUSIONS:Indometacin could inhibit the proliferation of Hela cell,block cell cycle at G0/G1 phase and induce apoptosis.

A new minimally invasive gallbladder-preserving operation has emerged for the treatment of gallbladder stones,but fundamentally it is a replica of the previous gallbladder preservation method.The gallbladder aids in digestion but is not essential for life.Its function should not be exaggerated and should not instigate trivial reasons for its preservation.Most patients undergoing cholecystectomy maintain a good quality of life.The causes,mechanisms,and prevention of gallstone formation remains mysterious,so a high recurrence rate after gallbladder-preserving operation is difficult to avoid.A full cholecystectomy can avoid recurrence complications and the benefits outweigh the risks.A discussion of the benefits and complications must be initiated to evaluate both treatment modalities for gallstones.

Objective To investigate the trend of cytokines in patients with hemophagocytic lymphohistiocytosis (HLH) and analyze its significance.Methods 16 patients with HLH from January 2011 to May 2013 were selected.The patients were divided into remission group and death group by prognosis.Serums of the two groups were collected when they were hospitalized and at 7 th,14 th,21st,28th and 42nd day during chemotherapy,and they were fractionated HLH 1-6 groups and HLH a-d groups again,then the levels of IL-18,IL-10,IL-12,NF-κB,TNF-α and neopterin were tested by enzyme linked immuno sorbent assay (ELISA) to analysis their trend.Results The levels of all of cytokines in the remission group declined with chemotherapy,the difference between HLH1 group and another HLH groups was statistically significant (P ＜ 0.05).In the death group,the levels of NF-κB,IL-12 and neopterin had no downward trend with chemotherapy,and the difference between HLHa group and another HLH groups was not statistically significant (all P ＞ 0.05).The level of TNF-α declined with chemotherapy,and the differences between HLHa group and HLHc group,HLHa group and HLHd group were statistically significant (P =0.049,0.000).The level of IL-10 declined sharply in the first week of chemotherapy,and the difference between HLHa group and HLHb group was statistically significant (P =0.00).The level of IL-18 declined after the 2nd-weeks' chemotherapy,and the differences between HLHa group and HLHb group,HLHa group and HLHc group were statistically significant (P =0.03,0.02).Conclusions In the remission patients,the levels of serum IL-18,IL-10,IL-12,NF-κB,TNF-α and neopterin declined after chemotherapy.In the death patients,the downward trend is not obvious.It was preliminarily confirmed that the prognosis of HLH is related to the trend of cytokines during chemotherapy.

Objective To explore the risk factors affecting prognosis of invasive fungal infection .Methods The clinical data of 208 hospitalized patients diagnosed with invasive fungal infection in Sun Yat-sen memorial hospital from 2007 to 2011 were reviewed . The factors affecting prognosis were determined by univariate and logistic regression analysis .Results The fatality rate of adult inpa-tient with invasive fungal infection was 21%.The univariate analysis showed that difference of seven indicators was significant between the survive group and death group:advanced age (over 60 years old), hospitalization time,fasting plasma glucose level, hypoalbumin-emia, using more than two kinds of broad spectrum antibiotic for more than two weeks , kinds of invasive operations , and multiple organ dysfunction syndrome ( MODS) .Binary logistic regression showed that the difference of five indicators was significant between the two groups:advanced age (over 60 years old), hypoalbuminemia, using more than two kinds of broad spectrum antibiotic for more than two weeks, kinds of invasive operations , and multiple organ dysfunction syndrome .Conclusions The indicators such as advanced age (over 60 years old), hypoalbuminemia, the use of more than two kinds of broad spectrum antibiotic for more than two weeks , kinds of invasive operations , and multiple organ dysfunction syndrome might be independent risk factors of death in patients with invasive fungal infection.Early medical intervention should be made in clinical work , in order to reduce fatality rate of patients with invasive fungal in-fection.

Objective To investigate the early diagnostic value of cornel confocal microscopy for the screening of small neuropathy in elderly patients with type 2 diabetic mellitus.Methods In the prospective study,96 elderly patients with diabetes as study group and 46 patients with non-diabetes as the control group were continuously collected from our hospital endocrinology and ophthalmology out patients during May 2014 to February 2016.The 96 cases of type 2 diabetes were subdivided into 47 patients with diabetic peripheral neuropathy (DPN)and 47 patients with nowdiabetic peripheral neuropathy(non DPN).Results The diabetes course was shorter in non-DPN group than in DPN group(P=0.000).The levels of glycosylated hemoglobin and urine albumin were lower in the nonDPN than in the DPN(P =0.072,0.007,respectively).The corneal nerve fiber density was lower in the DPN group than in NDPN group (P =0.000).Corneal nerve fiber density was higher in control group than in DPN and NDPN group.The differences in number of corneal nerve fibers showed no statistical significance between DPN and NDPN group (x2 =2.391,P =0.314).But the number of corneal nerve fibers was significant less in DPN and NDPN group than in control group(x2 =16.014,P =0.000).The negative correlation was found between the course of disease and corneal fibrous density by using single factor linear regression analysis.The number of corneal nerve fibers was lower in smoking group than in non-smoking group(P=0.003).The multiple linear regression analysis showed that duration of diabetes was a risk factor for diabetic neuropathy.Conclusions In some elderly diabetic patients with non-neuropathy,corneal nerve fiber density and number have been significantly decreased before nerve conductive velocity is reduced.Therefore,corneal confocal microscopy can be used to detect and diagnose small diabetic neuropathy in elderly patients with diabetes mellitus.

Objective To assess the effect of neutrophil?to?lymphocyte ratio ( NLR) on the recurrence rate of patients with alpha?fetoprotein (AFP) ?negative hepatocellular carcinoma (HCC) and the value of NLR in predicting prognosis. Methods The clinical data of seventy?seven patients diagnosed with AFP?negative HCC and treated with hepatocellular carcinoma surgery in the First Hospital in Weinan from June 2015 to March 2017 were analyzed. According to the recurrence at the end of the follow?up, the patients were divided into the recurrence group and the non?recurrence group. Cox single factor analysis was used to analyze the relationship between the clinicopathological features and postoperative recurrence, and the clinical risk factors with statistically significance in the univariate analysis were placed in the Cox multivariate regression analysis to determine whether it is independent risk factor. Results The differences between the two groups in the number of tumors (31/15,28/3),tumor size (>5 cm) (5. 53±1. 83,4. 65±1. 73),portal vein tumor thrombus (18/28,2/29),microvascular invasion (14/32,2/29) were all statistically significant (P<0. 05). Cox univariate analysis showed that preoperative NLR levels ( RR=1. 125, 95%CI 1. 052-1. 203, P=0. 029 ) , tumor number ( RR=0. 943,95%CI 1. 007-1. 330, P=0. 019 ) , tumor size (>5 cm ) ( RR=0. 550, 95%CI 0. 316-0. 956, P=0. 038),portal vein tumor thrombus (RR=1. 294,95%CI 1. 208-1. 386,P=0. 022),microvascular invasion (RR=1. 575,95%CI1. 209-2. 052,P=0. 028) were the risk factors of postoperative recurrence. Cox regression model showed that tumor number (RR=1. 830,95%CI 1. 184-2. 828,P=0. 026),portal vein tumor thrombus ( RR=2. 860,95%CI 2. 062-3. 968,P=0. 001) ,microvascular invasion ( RR=1. 760,95%CI 1. 019-3. 041,P=0. 037) and preoperative NLR level ( RR=1. 890,95%CI 1. 056-3. 383,P=0. 028) were independent risk factors of the recurrence in AFP negative HCC patients after surgery. Among the 77 patients,46 cases were in the recurrent group, the average value of NLR was 3. 49 ± 0. 30, and the average preoperative NLR of the non?recurrence group ( 31 patients ) were 3. 01 ± 0. 30, the difference between the two groups in NLR value was statistically significant (t=-6. 885,P=0. 000). According to the ROC curve,the NLR=3. 17 corresponded to the maximum Youden index,the sensitivity of NLR was 82. 6%,the specificity was 67. 7%. Conclusion The preoperative NLR level is inversely proportional to the recurrence?free survival time of patients with AFP?negative HCC,which is one of the independent risk factors for recurrence. The optimal critical value of NLR is 3. 17.

Objective To study the effect of Sildenafil in the treatment of hypoxemia after operation of cyanotic congenital heart disease.Methods A total of 34 cases with hypoxemia after operation of cyanotic congenital heart disease were collected between January 2009 to January 2015.They took Sildenafil with the dosage of 0.3-0.5 mg/kg every 6 hour.The change of heart rate (HR),systolic blood pressure (SBP),central venous pressure (CVP),pulmonary artery pressure (PAP),arterial partial pressure of oxygen [pa (O2)],arterial partial pressure of carbon dioxide [Pa (CO2)],oxygenation index [pa (O2)/FiO2],peak airway pressure (Ppeak),positive inotropic drug score (PIDS) and the lower bound of liver were observed at 4 time points,including before taking the medicine,after taking the medicine for 1 hour,after taking the medicine 1 day and after the ventilator was removed.Based on the data,the therapeutic effects of Sildenafil were studied.Results All 34 cases were cured.At the time point of 1 hour after taking Sildenafil,PAP,CVP and Ppeak decreased significantly,but pa (O2) and pa (O2)/FiO2 increased significantly (P ＜ 0.05).At the time point of 1 day after taking Sildinafil,SBP increased steadily,but PAP and CVP continued to get lower,and PIDS decreased significantly,while the liver lower bound was significantly reduced (P ＜ 0.05).At the time point of removing the ventilator,pa (O2) reached to (144.12 ± 26.25) mmHg,and hypoxemia was corrected,but PAP was reduced to (37.47 ± 3.77) mmHg,PIDS decreased to (17.56-± 1.94) scores,and heart failure was corrected.Compared with the previous 3 time points,there were statistically significant differences (P ＜ 0.05).Conclusion Sildenafil can highly selectively decrease pulmonary vascular resistance and obviously promote the correction of hypoxemia after operation of cyanotic congenital heart disease.

Objective To study the influence of different kinds of disinfection methods on antibacterial activity of TiO2 nanotubes. Methods TiO2 nanotubes were fabricated with 0.5%wt HF on pure titanium to acid-etching combined with an? odization as experimental group. The pure Ti was control group. They were disinfected by three kinds of disinfection meth?ods, which were alcohol immersion, autoclaving and UV irradiation. The bacterial adhesion ability was evaluated by observ?ing the morphology of samples, measuring the roughness and contracting angle. The film contact method was used to evaluate the antibacterial activity of samples with Staphylococcus aureus (Sa) after different infection treatment. The bacterial morphol?ogy was observed by field emission scanning electron microscope (FE-SEM). Results The treatment group has higher sur?face roughness. The bacterial adhesion ability of experimental group was stronger compared with that of control group. The contracting angle of samples exposed to UV irradiation was smaller than that of alcohol immersion and autoclaving treatment group. The viable count and FE-SEM showed that there were more bacteria and more complete morphology on the sample surface after alcohol immersion. The viable count was less and bacterial morphology suffered some damage on the sample sur?face after high pressure steam sterilization. The least viable count and the most complete destruction of bacterial morphology were found after ultraviolet (UV) germicidal irradiation. Conclusion UV irradiation shows the best antibacterial activity, the second is autoclaving and the worst is alcohol immersion.
